Abstract
To control tuberculosis in the world today an additional approach would be most welcomed. Preventing (or reducing) pulmonary cavity formation is one such approach that has been almost completely neglected. Pulmonary cavity formation and the extracellular growth of tubercle bacilli in cavities cause bronchial spread of the disease in adult patients and spread of the bacillus to the environment where they infect other people. Therefore, cavity formation perpetuates tuberculosis in mankind. If no cavities form, the patient is much less infectious. Also, cavity formation often allows the tubercle bacillus to multiply (extracellularly) to tremendous numbers. Therefore, in humans almost all multidrug-resistant tubercle bacilli develop in cavities. This communication reviews the literature on liquefaction and cavity formation, and lists some of the responsible hydrolytic enzymes. It also describes a simple method to identify inhibitory pharmaceuticals, i.e., to observe their effect on the liquefaction and ulceration of skin lesions produced in rabbits by ascending concentrations of live or dead tubercle bacilli.Entities:
